  In the combine described in Patent Document 1, the column cover is attached to the control unit after the lamp is assembled to the column cover. For this reason, for example, when confirming the lighting of the lamp, the column cover has to be attached to the control portion, which causes a problem in assembling workability. Furthermore, since the light is directly attached to the column cover, the column cover may be damaged, and it is necessary to be careful to prevent the column cover from being damaged.

  In addition, since the horn is provided on the control unit side, the sound pressure of the horn that is emitted from the horn and blown to the front of the column cover through the plurality of holes of the column cover can be reduced unless the column cover is attached. Could not check. For this reason, the alignment between the horn and the hole of the column cover is complicated, and there is a problem in assembling workability.

  Therefore, an object of the present invention is to provide a combine that solves the above-described problems by assembling a light and a horn to a resin cover to form a sub-assembly and then assembling the resin cover to a front cover.

A driving operation unit (7) for driving the combine (1);
A front cover (32) covering a front portion of the driving operation section (7);
A resin cover (40) removably supported by the front cover (32);
A light (41) that is detachably supported by the resin cover (40) and illuminates the front of the driving operation unit (7);
A horn (42) that is detachably supported by the resin cover (40) and emits a horn.
It is characterized by that.

  For example, referring to FIG. 6, the resin cover (40) has a horn cover (40b) that covers the front of the horn (42) attached to the resin cover (40) and has a plurality of holes (40c). .

For example, referring to FIG. 6, the light (41) is attached to the resin cover (40) via a first mounting bracket (47).
The horn (42) is attached to the resin cover (40) via a second attachment bracket (49) different from the first attachment bracket (47).

  In addition, although the code | symbol in the said parenthesis is for contrast with drawing, it does not limit the structure of this invention at all.

  According to the first aspect of the present invention, since the light and the horn are assembled to the resin cover to form a sub-assembly, the light and the horn can be easily assembled to the front cover via the resin cover. Thereby, the assembly workability | operativity of a light and a horn can be improved.

  According to the second aspect of the present invention, since the horn cover covering the front of the horn is formed on the resin cover, the horn cover can be easily formed integrally with the resin cover, and the horn and the plurality of holes are close to each other. Even if the plurality of holes are made small, the horn horn can be sufficiently blown in front of the front cover. For this reason, it is possible to reduce the intrusion of dust such as waste from a plurality of holes.

  According to the third aspect of the present invention, since the light and the horn are attached to the resin cover by different mounting brackets, it is possible to suppress the heat of the light from being transmitted to the horn, and to prevent the performance and deterioration of the horn due to the heat. Further, since the first mounting bracket and the second mounting bracket are separately configured, the respective shapes can be simplified and the cost can be reduced.

  As shown in FIG. 5, the front cover 32 can be rotated forward about the engaging pin 27a by removing the mounting screw 38 while being engaged with the engaging pin 27a. Then, with the front cover 32 opened forward by a predetermined angle, a holding portion (not shown) provided at the lower portion of the front cover 32 is hooked on the step frame 27 or the control frame 29 to hold the front cover 32 in an opened state. be able to.

  As shown in FIG. 6, an opening 35 is formed at the center of the front cover 32, and a rib 36 protruding slightly forward is formed around the opening 35 as shown in FIG. 3. Yes. The rib 36 is formed over substantially the entire width of the front cover 32. As shown in FIG. 6, a plurality of (four in the present embodiment) mounting bosses 37 having female threads are formed on the back side of the front cover 32 and around the ribs 36.

  A resin cover 40 is detachably supported on the mounting boss 37 of the front cover 32 via mounting screws 39. The resin cover 40 has a light hole 40a into which a light 41 that illuminates the front of the driving operation unit 7 is inserted, and a horn cover 40b that covers the front of the horn 42 that emits a horn.

  The horn cover 40b is formed with a plurality of holes 40c extending in the circumferential direction with different radii from the center of the circular horn cover 40b, and a horn emitted from the horn 42 is operated through the plurality of holes 40c. Sounded in front of part 7. On the back side of the resin cover 40, a plurality (three in this embodiment) of light mounting bosses 43 having female screws and a plurality of (two in this embodiment) horn mounting bosses having female screws are provided. 45 is formed.

  The light 41 is supported by a light mounting bracket 47 (first mounting bracket) so as to be rotatable about a rotation shaft 46, and the horn 42 is supported by a horn mounting bracket 49 (second mounting bracket). ing. The light 41 is attached to the light mounting boss 43 of the resin cover 40 via the light mounting bracket 47 by the mounting screw 50, and the horn 42 is connected to the horn of the resin cover 40 via the horn mounting bracket 49. It is attached to the attachment boss 45 with an attachment screw 51. That is, the light 41 and the horn 42 are detachably supported by the resin cover 40, and become a sub-assembly when attached to the resin cover 40.

  FIG. 7 is a perspective view showing a state in which the light 41 and the horn 42 are attached to the resin cover 40 and the resin cover 40 is attached to the front cover 32. As shown in FIG. 7A, the wiring 52 extends backward from the light 41, and a terminal 54 to which the wiring is connected is provided on the side of the horn 42.

  As shown in FIG. 7B, the wiring 52 extending from the light 41 is connected to the bundle wire W by the terminal 52 a, and the bundle wire W is also connected to the terminal 54 of the horn 42. Then, the bundled wires W are joined by the plurality of guides 55 at the joining portion 53 where the respective wires join. A connector 56 is provided at the end of the bundled wire W, and the connector 56 is connected to the wiring on the driving operation unit 7 side. Power and signals are supplied to the light 41 and the horn 42 via the bundled wire W and the wiring 52.

  Since the present embodiment is configured as described above, the worker first assembles the light 41 and the horn 42 to the resin cover 40 via the light mounting bracket 47 and the horn mounting bracket 49, respectively. At this time, since the light 41 is supported so as to be pivotable in the vertical direction around the pivot shaft 46, the outer periphery of the light 41 is automatically pressed by pressing the edge of the light hole 40a of the resin cover 40. The light 41 is configured so that the optical axis of the light 41 is aligned. A slight clearance is provided between the light 41 and the edge of the light hole 40a, and the optical axis of the light 41 can be manually adjusted.

  Moreover, since the light 41 is comprised by LED, there is little heat_generation | fever during lighting. In particular, heat generation on the front side which is the irradiation side of the light 41 can be suppressed, and even if an operator or the like touches the light 41, a burn or the like is not caused. Moreover, since the light 41 and the horn 42 are attached to the resin cover 40 by separate mounting brackets on the substrate side (back side) of the light 41, the heat of the light 41 is not transmitted to the horn 42, and the influence of the heat is affected. Can be reduced. The shape of the light mounting bracket 47 and the horn mounting bracket 49 can be simplified to reduce the processing cost, and the light 41 and the horn 42 can be provided close to each other. it can.

  On the other hand, the resin cover 40 is provided with a horn cover 40b in front of the assembled horn 42, and the horn cover 40b is provided with a plurality of holes 40c. Since the resin cover 40 is relatively small and simple in shape, the horn cover 40b and the plurality of holes 40c can be easily formed by injection molding or the like, and the cost can be reduced.

  Further, since the horn 42 is assembled to the resin cover 40, the horn cover 40b of the resin cover 40 and the horn 42 can be provided close to each other. For this reason, even if the plurality of holes 40c of the horn cover 40b are formed to be small, the horn of the horn 42 can be sufficiently blown in front of the front cover 32, and dust such as waste can enter from the plurality of holes 40c. It can reduce coming.

  Next, the operator assembles the resin cover 40 to which the light 41 and the horn 42 are attached and is sub-assembled to the front cover 32. Thus, since the light 41 and the horn 42, which are electrical components, are configured as a minimum unit assembly, the assembly workability of the light 41 and the horn 42 can be improved.

  For example, as compared with the case where the light 41 and the horn 42 are directly assembled to the front cover 32, the light 41 and the horn 42 are first assembled to the resin cover 40, so that the front cover 32 is attached when the light 41 and the horn 42 are assembled. It will not hurt. The resin cover 40 formed of resin and having few assembling portions can be easily assembled to the front cover 32 without damaging the front cover 32. Since the resin cover 40 can be easily assembled to the front cover 32, as shown in FIG. 5, the resin cover 40 can be assembled to the front cover 32 even when the front cover 32 is half-opened, and optical axis alignment is easy. Can be done.

  Further, for example, by connecting the bundled wire W connected to the sub-assembled resin cover 40 to the wiring on the driving operation unit 7 side, it is possible to confirm the lighting of the light 41 and the sound of the horn 42, and to assemble it. Workability can be improved. Moreover, since the light 41 and the horn 42 which are electrical components are collected, wiring can be simplified.

  Furthermore, when there are variations such as changing the number and arrangement of lights due to changes in specifications and classes, these variations can be realized by changing the shape of the resin cover 40. For example, the specification of one light and one horn and the specification of two lights can be realized by changing the resin cover 40. That is, when the shape of the large front cover 32 is changed, the cost is high. However, since the change of the small resin cover 40 is inexpensive, the cost can be reduced.

  Further, since the horn 42 is integrally assembled with the front cover 32 through the resin cover 40 formed as a sub-assembly, the positional relationship between the horn 42 and the plurality of holes 40c of the horn cover 40b is shifted, and the sound pressure of the horn 42 is reduced. It is possible to prevent the variation.

  And since the light 41 and the horn 42 are arranged in the surface direction of the front cover 32, the resin cover 40 is formed wide in the surface direction. For this reason, the attachment pitch with respect to the front cover 32 of the resin cover 40 can be enlarged easily, and support strength can be ensured. Furthermore, since the reinforcing ribs 36 are formed on the front cover 32, the resin cover 40 can be assembled stably. Thereby, resonance of the horn 42 can be prevented, the sound pressure of the horn 42 is stabilized, and the performance of the horn 42 can be ensured.

  Further, since the light 41 is disposed outside the body of the pre-processing unit 5 and inside the body of the horn 42, the light 41 can be prevented from being damaged by an obstacle or the like during traveling on the road or during cutting. Further, the ribs 36 function as a kite, so that the light 41 and the horn 42 can be prevented from getting wet by rain or the like. Further, since the resin cover 40 is formed wide in the surface direction, the front-rear width of the sub-assembly component can be suppressed, and the front cover 32 protrudes greatly forward, which is an obstacle when an operator sees the divider 13 or the like. Can be prevented.

  Moreover, since the front cover 32 and the resin cover 40 are configured separately, each can be configured with an optimal material. For example, the front cover 32 can be made of a resin material resistant to impact, and the resin cover 40 can be made of a resin material resistant to heat.

  In addition, in this Embodiment, although the light 41 is arrange | positioned rather than the horn 42 inside a body, the reverse may be sufficient. Further, the rib 36 may not be formed on the front cover 32. Furthermore, the shapes of the front cover 32 and the resin cover 40 are not limited. The number of lights 41 and horns 42 is not limited to one and may be two or more.
